  1. 1. Waste Textiles Bioprocessing to Ethanol and Biogas

    Author : Azam Jeihanipour; Högskolan i Borås; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; bioethanol; biogas; biorefinery; cellulose recalcitrance; cotton-based cellulose; enzymatic hydrolysis; pretreatment; recycling; waste textile; Resursåtervinning; Resursåtervinning; Resource Recovery; waste textile.;

    Abstract : The work of the present thesis focused on conversion of the cellulosic part of waste textiles into biogas and ethanol, and its challenges. In 2009, the global annual fiber consumption exceeded 70 Mt, of which around 40% consisted of cellulosic material. READ MORE

  2. 2. Exploring Anaerobic Bacteria for Industrial Biotechnology - Diversity Studies, Screening and Biorefinery Applications

    Author : Rosa Aragao; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Anaerobic bacteria; industrial biotechnology; biorefinery; microbial diversity; single cell entrapment; llama rumen;

    Abstract : Depletion of easily accessible fossil energy resources, threat of climate change and political priority to achieve energy self-sufficiency and sustainable solutions prioritize a conscious and smart use of renewable resources to generate a bio-based economy. Bio-based compounds can replace chemicals and fuels that are now mainly produced from crude oil. READ MORE

  3. 3. Aspects of Ash Transformations in Pressurised Entrained-Flow Gasification of Woody Biomass : Pilot-scale studies

    Author : Charlie Ma; Marcus Öhman; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; woody biomass; gasification; ash transformation; slag behaviour; refractory corrosion; Energy Engineering; Energiteknik;

    Abstract : Pressurised entrained-flow gasification (PEFG) of woody biomass has the potential to produce high purity syngas for the production of vital chemicals, e.g., biofuels. However, ash-related issues such as reactor blockages and refractory corrosion need to be addressed before this potential can be realised from a technical perspective. READ MORE

  4. 4. Application of fuel design to mitigate ash-related problems during combustion of biomass

    Author : Anders Rebbling; Christoffer Boman; Dan Boström; Marcus Öhman; Nils Skoglund; Sonja Enestam; Umeå universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermochemical energy conversion; biomass; combustion; ash chemistry; fuel design; ash transformation reactions; renewable energy;

    Abstract : The energy supply of today is, through the use of fossil energy carriers,contributing to increased net emissions of greenhouse gases. This hasseveral negative effects on our environment and our climate. In order toreduce the impact of this, and possibly to reverse some of the effects, allrenewable energy sources must be used.
